Okay here's the deal. I have just about replaced every part and cleaned out every part on the carb on this thing and my arm is getting a little tired of cranking. Problem: It will start but only run for about 15 seconds then quits. Then I have to pull a bunch more times to get it to start and it does the same thing. Tried changing the jet settings but it doesn't even seem to effect it. Did notice that if I unplug the fuel line there is some sort of linkage that opens and closes something in the float bowl. And I have checked the fuel pump and it's working well.<br /><br /> Here is what I think could be wrong:<br /><br />Installed something backward on the carb? Don't know how I could have but you never know.<br /><br />And that's it! That's all I can think of. My only problem is I don't have a diagram of how it should be together. <br />Anybody have a diagram.<br /><br />Maybe the previous owner put something back together wrong?
